Amazon Prime Music allows you to stream over one million songs to your iOS, Android, or Kindle Fire device in addition to your desktop/notebook computer (looks like Windows Phone is left out yet again, and as for BlackBerry, well…). In addition unlimited and ad-free play, you can download any of the streaming songs to listen to while offline.

It should also be noted that the service is only available to those who cough up the $99 yearly price of admission for Prime -- there's won't be a "dumbed down," ad-supported version for non-Prime listeners.

But please do keep this in mind; Prime Music’s library is still woefully “inadequate” compared to competitors like Spotify (20+ million songs) or Xbox Music (30+ million songs). Also keep in mind that because of an ongoing disagreement between the two parties, artists signed with Universal Music Group are currently omitted from Prime Music. That means if you're a fan of a wide range of artists like Jay-Z, Taylor Swift, U2, Stevie Wonder, or even Elvis Costello, you won’t get any love from Prime Music... for now.

But since most tech heads are already paying for an Amazon Prime subscription anyway (which includes “free” expedited shipping, streaming TV shows/movies, and Kindle eBook lending), the small library size of Amazon Prime Music or lack of Universal Music Group artists likely won’t be seen as a hindrance.
